Light Spread of Giesemann

[spikehs]

So now that I've been a whole week without my tank up and running at full capacity, I've started to plan out my tank for when I can set it up again. I'm thinking of something around 150g range, give or take... I was curious as to what you all thought the maximum spread of this unit could do? Give that I won't have anything near the edges (I like having lots of open sand if possible)... I just want to make sure the light looks evenly spread, even if the intensity is not there.... i was thinking of something like 60l x 30w x 20h?

That's a sweet looking fixture! I love how the T5's are angled in.
